1. Safety Precautions 1

1.Safety Precautions PLEASE READ THESE SAFETY PRECAUTIONS!

RF Energy Health Hazard

This symbol indicates a risk of personal injury due to radio frequency exposure. The radio equipment described in this guide uses radio frequency transmitters. Do not

allow people to come in close proximity to the front of the antenna while the transmitter is operating. The antenna will be professional installed on fixed-mounted out d oor permanent structures to provide separation from any other antenna and all persons.

WARNING: RF Energy Exposure Limits and Applicable Rules for 6-38 GHz. It is recommended that the radio equipment operator refer to the RF exposure rules and precaution for each frequency band and other applicable rules and precautions with respect to transmitters, facilities, and operations that may affect the environment due to RF emissions for each radio equipment deployment site.

Appropriate warning signs must be properly placed and posted at the equipment site and access entries.

Protection from Lightning

Article 810 of the US National Electric Department of Energy Handbook 1996 specifies that radio and television lead-in cables must have adequate surge protection at or near the point of entry to the building. The code specifies that any shielded cable from an external antenna must have the shield directly connected to a 10 AWG wire that connects to the building ground electrode.

Do not turn on power before reading Moseley’s product documentation. This device has a 48 VDC direct current input.

Protection from RF Burns

It is hazardous to look into or stand in front of an active antenna aperture. Do not stand in front of or look into an antenna without first ensuring the associated transmitter or transmitters are switched off. Do not look into the waveguide port of an ODU (if applicable) when the radio is active.

2 1. Safety Precautions

Risk of Personal Injury from Fiber Optics

DANGER: Invisible laser radiation. Avoid direct eye exposure to the end of a fiber, fiber

cord, or fiber pigtail. The infrared light used in fiber optics systems is invisible, but can cause serious injury to the eye.

WARNING: Never touch exposed fiber with any part of your body. Fiber fragments can enter the skin and are difficult to detect and remove.

Warning – This is a Class A product

WARNING: This is a Class A product. In a domestic environment this product may cause

radio interference in which case the user may be required to take adequate measures.

Warning – Turn off all power before servicing

WARNING: Turn off all power before servicing.

Safety Requirements

2.1About This Manual

This manual is written for those who are involved in the “hands-on” installation of the EVENT HD in a microwave point-to-point link, such as installation technicians, site evaluators, project managers, and network engineers. It assumes the reader has a basic understanding of how to install hardware, use Windows® based software, and operate test equipment.

2.2Introduction

The Moseley family of digital radios provides high capacity transmission, flexibility, features, and convenience for wireless digital communications networks. The Moseley digital point-to-point radios represent a new microwave architecture that is designed to address universal applications for video, audio, data, PDH and SDH platforms. This advanced technology platform is designed to provide the flexibility to customers for their current and future network needs.

The Moseley EVENT HD is a digital microwave radio terminal composed of a Software Defined Indoor Unit™ (SDIDU™) and Outdoor Unit (ODU). The SDIDU is common to all product lines whereas the ODU, the radio transceiver unit which establishes the frequency of operation, is selected by application and model. The ODU is fully interchangeable covering the licensed 2, 7, 13, 18, and 23 GHz bands as well as the unlicensed 5.3 and 5.8 GHz ISM bands. Some applications are:

Broadcast STL (Studio-to-Transmitter Link) and BAS (Broadcast Auxiliary Service) for for licensed half-duplex applications, FCC part 74.602, for data rates to 150 Mbps,

 2 GHz band between 1990 to 2110 MHz in 12 MHz and 17 MHz channels.  6.5 GHz band between 6425 to 6525 MHz in 25 MHz channels.  7 GHz band between 6825 to 7125 MHz in 25 MHz channels.  13 GHz band between 12.7 to 13.25 GHz in 25 MHz channels.

Power Supply Input

DC Input

-48 VDC

48v (Isolated Input); 2-pin captive power connector. The Software Defined IDU™ requires an input of 48 volts dc ±10% at the rear panel DC Input connector. The total required power is dependent on the option cards and protection configuration (1+0, 1+1). Th e SDIDU

rear panel power connector pin numbering is 1 through 2, from left to right, when facing the unit rear panel. Pin 1 is the power supply return and is connected to unit chassis ground internally. Pin 2 should be supplied with a nominal 48 V dc, with respect to the unit chassis (ground). A ground-isolated supply may be used, provided it will tolerate grounding of its most positive output.

The recommended power input is 44 to 52 V dc at 2 Amps minimum. It is recommended that any power supply used be able to supply a minimum of 100 W to the SDIDU

A mating power cable connector is supplied with the Software Defined IDU™. It is a 2-pin plug, 5 mm pitch, manufactured by Phoenix Contact, P/N 17 86 83 1 (connector type MSTB 2,5/2-STF). This connector has screw clamp terminals that accommodate 24 AWG to 12 AWG wire. The power cable wire should be selected to provide the appropriate current with minimal voltage drop, based on the power supply voltage and length of cable required. The recommended wire size for power cables under 10 feet in length supplying 48 Vdc is 18 AWG.

The SDIDU via the ODU/SDIDU Defined IDU™

supplies the ODU with all required power

Interconnect cable. The Software

does not have a power on/off switch. When DC power is connected to the SDIDUTM, the digital radio powers up and is operational. There can be up to 320 mW of RF power present at the antenna port (external antenna version). The antenna should be directed safely when power is applied.

2.4.5ODU LED Indicators

The ODU 2200, 6500, and 7200 has an externally visible LED meter that provides both RSL (Receive Signal Level) and transmit power. For full-duplex operat ion the ODU meter displays RSL on the top bar and transmit level on the bottom bar as shown in Figure 2-4.

Figure 2-4. ODU 2200 RSSI Output vs. Received Signal.

16 2. System Description

The upper RSL LED meter is calibrated to represent exactly 10 dB for each LED, going from -95 dBm at the far left (red) to -15 dBm at the far right (green). The brightness of each LED is modulated for levels between 0 to 10 dB such that th e far left LED will be fully extinguished at -95 dBm and the far right LED will be fully illuminated at -15 dBm. When the RSL is in the red region (<-75 dBm) the signal level is approaching or has reached threshold (depends on modulation type).

The transmit LED indicates full power will all 8 LEDs illuminated to minimum power with 1 LED illuminated. For simplex applications the both rows indicate either RSL or transmit power.

2.5System Description

The overall Event-HD digital radio architecture consists of a single 1RU rack mount Software Defined Indoor Unit

(SDIDUTM) with a cable connecting to an Outdoor Unit (ODU). The IF signal between the SDIDU and ODU operates at a relatively low frequen cy compared with the RF signal allowing for extensive cable runs in excess of 250 m with inexpensive coaxial cable with no degradation in radio performance.

The Event-HD ODU is mounted to a fixed or telescoping antenna mast near the desired antenna location providing a short cable run between ODU and antenna at the RF frequency. This SDIDU /ODU architecture is advantageous when compared to a single IDU (no ODU) with external mount antenna as operating at these RF frequencies from the IDU rack to the antenna will result in sign ificant signal degradation and require expensive low-loss coaxial cable or waveguide.

18 2. System Description

The Event-HD ODU RF Up/Down Converter provides the interface to the antenna. The transmit section up converts and amplifies the modulated Int ermediate Frequency (IF) of 350 MHz from the IF Processor and provides additional filtering. The receive section down converts the received signal, provides additional filtering, and outputs an IF of 140 MHz to the IF Processor.

The Event-HD digital radio modem performs QPSK, 16-QAM, 32-QAM, 64-QAM, and 128QAM modulation and demodulation of the payload and forward error correction using advanced modulation and coding techniques. Using all-digital processing, the IF Modem uses robust modulation and forward error correction coding to minimize the number of bit errors and optimize the radio and network performance. The IF Modem also scrambles, descrambles and interleaves/deinterleaves the data stream in accordance with Intelsat standards to ensure modulation efficiency and resilience to sustained burst errors. The modulation will vary by application, data rate, and frequency spectrum. The highest order modulation mode supported is 128 Quadrature Amplitude Modulation (QAM). Table 2-5 summarizes the TCM/convolutional code rates for each modulation type supported by the Event-HD.

The major functions of the SDIDU

• I/O Processing – Event-HD digital radio comes with a standard I/O capability that

includes support for up to 16xT1/E1 and 2x100Base-TX user payloads, 2x100Base-TX for SNMP, and voice orderwire. In addition, option cards for DVB-ASI, DS-3/E3/STS1, 1-2 x STM-1/OC-3, and 4xDS-3/E3/STS-1 may be added. The Event-HD architecture is flexible and allows for the addition of other I/O types in the future.

• Switch/Framing – The Event-HD digital radio includes an Ethernet Switch and a

proprietary Framer that are designed to support 1+1 protection switching, ring architecture routing, and overall network control functions.

• Network Processor – The Event-HD digital radio includes a Network Processor which

performs SNMP and Network Management functions.

can be summarized as follows:

• Modem/IF – The Event-HD digital radio modem performs forward-error-correction

(FEC) encoding, PSK/QAM modulation and demodulation, equalization, and FEC decoding functions. The IF chain provides a 350 MHz carrier and receives a 140 MHz

2. System Description 19

carrier. The multiplexer function is built into an appliqué t hat resides in the Modem/IF Module. Two modems can be used for 1+1 protection or ring architectures.

• Power Supply – The Event-HD power supply accepts 48 Vdc and supplies the SDIDU

and ODU with power. A second redundant power supply may be added as an optional module.

The Modem Processor and its associated RAM, ROM, and peripherals control the digital and analog operation. It also provides configuration and control for both the IF and I/O cards. The SDIDU interfaces with the ODU to receive and provide modulated transmit and receive waveforms.

The Event-HD digital radio also provides the physical interface for the user payload and network management. In transmit mode, the Framer merges user payload (OC-3 or Fast Ethernet) with radio overhead-encapsulated network management data. This combined data stream is transmitted without any loss of user bandwidth. In the receive mode, the Framer separates the combined data stream received from the 256-QAM Modem. The SDIDU data interface port. The SDIDU

supports Scalable Ethernet data rates, such as 25 or 50 Mbps via the 100BaseT

provides network management data on 10 Mbps ports accessible via the 10/100BaseTX port. The Central Processor Unit (CPU) provides the embedded control and network element functionality of the OAM&P. The CPU also communicates with other functions within the SDIDU status monitoring. The CPU passes appropriate status information to the SDIDU

for configuration, control, and

rear

panel display. The power supply converts -48 Vdc to the DC voltage levels required by each component

in the system.

2.6Consecutive Point Architecture

The consecutive point network architect ure is based upon the proven SONET/SDH ring. Telecommunications service providers traditionally use the SONET/SDH ring architecture to implement their access networks. A typical SONET/SDH network consists of the service provider’s Point of Presence (POP) site and several customer sites with fiber optic cables connecting these sites in a ring configuration (see Figure 2-6). This architecture lets providers deliver high bandwidth with high availability to their customers.

20 2. System Description

Figure 2-6. Ring Configuration

SONET/SDH rings are inherently self-healing. Each ring has both an active path and a standby path. Network traffic normally uses the active path. If one section of the ring fails, the network will switch to the standby path. Switchover occurs in seconds. There may be a brief delay in service, but no loss of payload, thus maintaining high levels of network availability.

The consecutive point architecture implemented in the Moseley Digital Radio family is based on a point-to-point-to-point topology that mimics fiber rings, with broadband wireless links replacing in-ground fiber cable. A typical consecutive point network consists of a POP and several customer sites connected using Software Defined IDU™. These units are typically in a building in an east/west configuration. Using east/west configurations, each unit installed at a customer site is logically connected to two other units via an over-the-air radio frequency (RF) link to a unit at an adjacent site.

Each consecutive point network typically starts and ends at a POP. A pattern of wireless links and in-building connections is repeated at each site until all buildings in the network are connected in a ring as shown for an ethernet network in Figure 2-7. For 2 x 1+0 and 2 x 1+1 nodes payload and NMS connections need to be jumpered between two SDIDU

. For 1 x 2+0 nodes, there is no need for jumpers as there is a single SDIDUTM. For SDH or SONET payloads, the configuration is similar but an external add/drop mux is required.

2.72 + 0 (East-West) Configuration

The Event-HD supports a 2+0, or east-west, configuration that allows a consecutive point architecture to be achieved with only a single 1 RU chassis at each location. In this configuration the SDIDU One modem is referred to as the west modem and the other as the east modem. The SDIDU

ring architecture and the other broadcasting/receiving in the other as shown in Figure 2-8.

Figure 2-8. 2 + 0 (East West) Configuration

2.8Spanning Tree Protocol (STP)

Spanning Tree Protocol (STP) keeps Ethernet loops from forming in a ring architecture. Without STP, loops would flood a network with packets. STP prevents loops by creating an artificial network break. In the event of a network outage, STP automatically removes the artificial break, restoring connectivity.

22 2. System Description

2.91+1 Protection

The Event HD supports 1+1 protection as an option for a critical link. In this configuration, protection is provided in a single 1 RU chassis. The SDIDUTM contains two power supplies and two modems. The power supply, ODU, IF/telemetry and modem are protected. The digital framing and LIUs are not. One modem is referred to as the west modem and the other as the east modem. 1+1 protection can be run in two modes called Protected Non-Diversity and Protected Diversity.

2.9.1Protected Non-Diversity (Hot Standby)

Figure 2-9 shows operation in Protected Non-Diversity mode, also called Hot Standby. In this mode, one ODU at each location transmits to two ODUs at the other location. This mode does not require the extra bandwidth or interference protection. It provides hitless receive switching and hot standby. The SDIDU upon appropriate ODU alarm or ODU interface error, minimizing transmit outage time.

automatically switches transmit ODU

2.9.2Protected Diversity

In Protected Diversity mode, the link between each pair of modems is the same, as shown in Figure 2-10, providing complete redundancy. This arrangemen t requires bandwidth for both links and non-interference between the links, but it provides hitless receive and transmit switching. The SDIDU

supports both frequency and spatial

diversity.
